Hello, my name's Lewis Dartnell, the author of the popular science book 'The Knowledge: How to Rebuild our World from Scratch' (book website link). Welcome to the book's discussion forum! Get a drink, make yourself comfortable, and join the conversation. New members will need to register first, using the link in the top bar. If you like you can then introduce yourself in the forum in this Welcome category, and then head over to any of the discussion forums. There are some general chat rooms, as well as specific forums for the themes of the different book chapters.

What do you think the book missed out? What vital knowledge do you consider the most critical to attempt to preserve, just in case? What recommendations do you have for people to read, watch or listen to?
